The Book of Vayikra (Leviticus):
Chapter 16

1 And HaShem spoke unto Moses, after the death of the two
sons of Aaron, when they drew near before HaShem, and died;

2 and HaShem said unto Moses: 'Speak unto Aaron thy brother,
that he come not at all times into the holy place within the veil, before the
ark-cover which is upon the ark; that he die not; for I appear in the cloud upon
the ark-cover.

3 Herewith shall Aaron come into the holy place: with a young
bullock for a sin-offering, and a ram for a burnt-offering.

4 He shall put on the holy linen tunic, and he shall have the
linen breeches upon his flesh, and shall be girded with the linen girdle, and
with the linen mitre shall he be attired; they are the holy garments; and he
shall bathe his flesh in water, and put them on.

5 And he shall take of the congregation of the children of
Israel two he-goats for a sin-offering, and one ram for a burnt-offering.

6 And Aaron shall present the bullock of the sin-offering,
which is for himself, and make atonement for himself, and for his house.

7 And he shall take the two goats, and set them before HaShem
at the door of the tent of meeting.

8 And Aaron shall cast lots upon the two goats: one lot for
HaShem, and the other lot for Azazel.

9 And Aaron shall present the goat upon which the lot fell
for HaShem, and offer him for a sin-offering.

10 But the goat, on which the lot fell for Azazel, shall be
set alive before HaShem, to make atonement over him, to send him away for Azazel
into the wilderness.

11 And Aaron shall present the bullock of the sin-offering,
which is for himself, and shall make atonement for himself, and for his house,
and shall kill the bullock of the sin-offering which is for himself.

12 And he shall take a censer full of coals of fire from off
the altar before HaShem, and his hands full of sweet incense beaten small, and
bring it within the veil.

13 And he shall put the incense upon the fire before HaShem,
that the cloud of the incense may cover the ark-cover that is upon the
testimony, that he die not.

14 And he shall take of the blood of the bullock, and
sprinkle it with his finger upon the ark-cover on the east; and before the
ark-cover shall he sprinkle of the blood with his finger seven times.

15 Then shall he kill the goat of the sin-offering, that is
for the people, and bring his blood within the veil, and do with his blood as he
did with the blood of the bullock, and sprinkle it upon the ark-cover, and
before the ark-cover.

16 And he shall make atonement for the holy place, because of
the uncleannesses of the children of Israel, and because of their
transgressions, even all their sins; and so shall he do for the tent of meeting,
that dwelleth with them in the midst of their uncleannesses.

17 And there shall be no man in the tent of meeting when he
goeth in to make atonement in the holy place, until he come out, and have made
atonement for himself, and for his household, and for all the assembly of
Israel.

18 And he shall go out unto the altar that is before HaShem,
and make atonement for it; and shall take of the blood of the bullock, and of
the blood of the goat, and put it upon the horns of the altar round about.

19 And he shall sprinkle of the blood upon it with his finger
seven times, and cleanse it, and hallow it from the uncleannesses of the
children of Israel.

20 And when he hath made an end of atoning for the holy
place, and the tent of meeting, and the altar, he shall present the live goat.

21 And Aaron shall lay both his hands upon the head of the
live goat, and confess over him all the iniquities of the children of Israel,
and all their transgressions, even all their sins; and he shall put them upon
the head of the goat, and shall send him away by the hand of an appointed man
into the wilderness.

22 And the goat shall bear upon him all their iniquities unto
a land which is cut off; and he shall let go the goat in the wilderness.

23 And Aaron shall come into the tent of meeting, and shall
put off the linen garments, which he put on when he went into the holy place,
and shall leave them there.

24 And he shall bathe his flesh in water in a holy place and
put on his other vestments, and come forth, and offer his burnt-offering and the
burnt-offering of the people, and make atonement for himself and for the people.

25 And the fat of the sin-offering shall he make smoke upon
the altar.

26 And he that letteth go the goat for Azazel shall wash his
clothes, and bathe his flesh in water, and afterward he may come into the camp.

27 And the bullock of the sin-offering, and the goat of the
sin-offering, whose blood was brought in to make atonement in the holy place,
shall be carried forth without the camp; and they shall burn in the fire their
skins, and their flesh, and their dung.

28 And he that burneth them shall wash his clothes, and bathe
his flesh in water, and afterward he may come into the camp.

29 And it shall be a statute for ever unto you: in the
seventh month, on the tenth day of the month, ye shall afflict your souls, and
shall do no manner of work, the home-born, or the stranger that sojourneth among
you.

30 For on this day shall atonement be made for you, to
cleanse you; from all your sins shall ye be clean before HaShem.

31 It is a sabbath of solemn rest unto you, and ye shall
afflict your souls; it is a statute for ever.

32 And the priest, who shall be anointed and who shall be
consecrated to be priest in his father's stead, shall make the atonement, and
shall put on the linen garments, even the holy garments.

33 And he shall make atonement for the most holy place, and
he shall make atonement for the tent of meeting and for the altar; and he shall
make atonement for the priests and for all the people of the assembly.

34 And this shall be an everlasting statute unto you, to make
atonement for the children of Israel because of all their sins once in the
year.' And he did as HaShem commanded Moses.
